Vitamin K  

Vitamin K- plays a critical role in maintaining healthy bone density. Vitamin K promotes both bone and arterial health also supports healthy calcium balance . Our Super K provides the three forms of vitamin K that can be utilized by the body: vitamin K1 and dual forms of K2, MK-4 and MK-7. The MK-4 form is the most rapidly absorbed type of vitamin K. However, it only lasts in the bloodstream for a few hours. In contrast, the MK-7 form is available to the body for a full 24-hour period at much higher levels. The low ( below 50 mcg )dose vitamin K2 Mk-7has, is safe for people taking blood thinners and anticoagulants. According to the clinical research,it has just little effect on blood coagulation. That is why Life Extension has developed a Low-Dose Vitamin K2 (MK-7), which contains 45 mcg of vitamin K2 Mk-7.
